most cells underego apoptosis if their dna is damaged. How can this be beneficial to an organism? someone pls help
Answer:
It prevents the cell from passing on those defects to other cells through DNA replication in cell division. By self destructing before it gets the chance to divide, whatever problem the cell had ends right there and doesn't propagate in the organism.

Geoengineering includes a variety of large-scale efforts to reverse global climate change.
One geoengineering concept involves releasing large amounts of iron-containing
fertilizers into oceans. The increased concentration of iron in ocean water would
theoretically increase the rate of photosynthesis carried out by phytoplankton. Why are
such ideas controversial?
A. Photosynthetic algae would increase, not decrease, atmospheric carbon
dioxide.
C. Scientists cannot agree whether carbon dioxide in the atmosphere relates to
global climate change.
D. Scientists cannot predict what other unintended effects large concentrations
of iron may have.
Answer: D, Scientists cannot predict what other unintended effects large concentrations
of iron may have.

A sperm cell has a tail 40 micrometers long and a student draws it 40mm long. Calculate the magnification
Answer:
The formula for calculating magnification is:
Magnification = Size of drawing / Actual size
Size of drawing = 40 mm
Actual size = 40 micron meter
Convert 40 mm to micron unit: 40 * 1000 = 40,000 micron
Magnification = 40,000 / 40 = 1000.
The magnification is 1000 X.
This answer means that the drawing is 1000 times bigger than the actual size of the cell.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
competition
random chance
being the luckiest
Answer:
competition
Explanation:
An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).
A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.
Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
PLS ANSWER How is sunlight important in your life? Describe some of the positive and negative effects of sunlight.
Answer:
Sunlight is important in my life because you need it if you have a plant and you want to take care of the plant.Postive effects of sunlight is Sun water and needing health
Answer:
I know one reason is that plants need sunlight, and without plants we would all die. This is because plants need sun, and if we didn't have plants, we would be robbed of that resource, and then animals who eat the plants would die, so meat would be taken from us as well and we would all DIE.
For stars in the main sequence, which color of stars tend to have higher absolute brightness? (2 points)
The HR diagram is shown with Absolute Brightness on the y axis from negative four to six and Surface Temperature on the x axis from 40,000 to 2,500 degrees Celsius. There are several dots plotted between four and six absolute brightness and 10,000 to 2,500 degrees Celsius labeled Supergiants. There are several dots plotted between 1.5 and three absolute brightness and 7,500 to 2,500 degrees Celsius labeled Giants. There are several dots plotted between negative four and negative two absolute brightness and 30,000 to 7,500 degrees Celsius labeled Dwarfs. Down the middle, there are several dots plotted diagonally from ordered pair 40,000 and five down to 2,500 and negative three labeled Main Sequence.
White stars
Yellow stars
Blue stars
Red stars
Answer:
Blue Stars
Explanation:
Hope this helps :)
Blue stars tend to have higher absolute brightness for stars in the main sequence.
What is absolute brightness?Absolute brightness, also known as absolute magnitude, is a measure of the luminosity of a celestial object such as a star or planet, expressed as an apparent magnitude that the object would have if it were placed at a standard distance of 10 parsecs (32.6 light-years) away from Earth.
It is an objective measure of an object's intrinsic brightness, independent of its distance from Earth. Absolute brightness is a useful tool in astrophysics for comparing the luminosities of stars and determining the distance to remote stars and galaxies. It provides a standardized method of comparison, allowing scientists to study the evolution and distribution of stars and galaxies throughout the universe.

Humoral immunity is a type of adaptive immunity that results in the circulation of which of the following throughout the blood?
A. antigens
B. macrophages
C. natural killers
D. antibodies
Answer:
Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.
Antibodies is circulated throughout the blood in Humoral immunity.
B cells changed into plasma B cells that is responsible for the production of antibodies against a specific microbe such as bacteria and virus etc. The humoral immune system attacks and controls the antigens that are present outside the infected cells. Humoral immunity is also known as antibody-mediated immunity so it is concluded that antibodies provides immunity in humoral immunity system.

What are TWO factors that could affect the rate of diffusion?
Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.

What happen to the brain and the brain cavity?
Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

The cranial cavity, also known as intracranial space, is the space within the skull that accommodates the brain. The skull minus the mandible is called the cranium. The cavity is formed by eight cranial bones known as the neurocranium that in humans includes the skull cap and forms the protective case around the brain.

Answer:
There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
